Hi, I have over 52 mins of 3840x2160 pixels video made in front of Green Background. Currently I am using After Effects multiple features for removing the Green background. But when I import this After Effect project in Premiere Pro CC for editing (giving various backgrounds) then the System becomes very slow - almost unworkable. I am using 27 inch IMac with 4 Ghz core i7 processor, 32 GB Ram @ 1600 MHz DDR3 & 1 TB SSD. I have also tried first making an alpha video by rendering this AE project in Premiere Pro in 3840x2160 pixels by using Animation option for rendering. Although I am able to edit this alpha channel file in Premiere Pro but the problems are multiple. a) Renderning 52 minutes of 3840x2160 pixels AE project in Premiere Pro takes more than 35 hours. b) It alpha file requires huge huge space on my SSD. Is there a better & efficent way of doing it? I will be really obliged for kind assistance. Qamar
